NOTES: Only trips in
which the transportation mode could be identified in both travel directions
are considered.

The percentages in this table for going trips by return trips of
the same mode do not match the percentages in Table 7 for same mode trips in
each direction, because the two tables use a different base for figuring
percentages. The data in this table
are arrayed directionally (going x return), while the percentages in table 7
are based on the total number of trips via each mode in both directions
combined.

The difference between shaded cells on the same row are not
statistically significant, except for going mode train, the percentages for
return mode personal vehicle and bus, and for going mode personal vehicle and return mode other, are
statistically different. All other
shaded cells on the same row are not statistically different.

Underlined
estimates are based on a small sample size (<30) or a coefficient of
variation greater than 30% and are not reliable.
